Oxidative stress effects in the uterus, placenta and fetus of pregnant rats submitted to acute and chronic stress

Acta cir. bras; 33 (9), 2018
Abstract Purpose: To evaluate the effects of oxidative stress in pregnant rats submitted to acute and chronic stress, relating to alterations in the uterus, placenta and fetus. Methods: Twenty-four female Wistar albino (Rattus norvegicus), were divided into four groups, for induction of oxidative str...

Oxidative stress on ischemia/reperfusion injury in mice with non-alcoholic hepatic steatosis or steatohepatitis

Acta cir. bras; 33 (9), 2018
Abstract Purpose: To evaluate the oxidative stress, resulting from ischemia and hepatic reperfusion, in mice with non-alcoholic hepatic steatosis and steatohepatitis. Methods: C57BL/6 male mice were used. Part of them were ob/ob mice, and the other part was fed with standard or MCD diets - this last ...

Antioxidant response of cowpea co-inoculated with plant growth-promoting bacteria under salt stress

Braz. j. microbiol; 49 (3), 2018
Abstract Soil salinity is an important abiotic stress worldwide, and salt-induced oxidative stress can have detrimental effects on the biological nitrogen fixation. We hypothesized that co-inoculation of cowpea plants with Bradyrhizobium and plant growth-promoting bacteria would minimize the deleterious ...

Cold water immersion and inflammatory response after resistance exercises

Rev. bras. med. esporte; 24 (5), 2018
INTRODUCTION: High-intensity resistance exercises (RE) cause an inflammatory response that reduces functionality. OBJECTIVE: To evaluate the effects of Cold Water Immersion (CWI) on leukocytosis, oxidative stress parameters, inflammatory markers and delayed onset muscle soreness (DOMS) resulting from a R...

Entrenamiento físico de alta intensidad en maratonistas produce mayor remodelado cardíaco y reduce respuesta de estrés oxidativo

Rev. chil. cardiol; 37 (2), 2018
Resumen: Introducción: El ejercicio físico reduce la mortalidad cardiovascular y genera remodelado cardíaco. Altas cargas de entrenamiento pueden generar remodelado cardíaco adverso. Biomarcadores (BMC) de inflamación Interleukina 6 (IL-6) y de estrés oxidativo Malondialdehído (MDA), potencialmen...

Sepsis-induced acute kidney injury: kidney protection effects by antioxidants

Rev. bras. enferm; 71 (4), 2018
ABSTRACT Objective: To evaluate the antioxidant action of N-acetylcysteine and diosmin-hesperidin in an experimental model of sepsis-induced acute kidney injury in rats. Methods: The study used 20 Wistar adult male rats divided into the following groups: control (laparotomy with no induction of abdomin...

Low serum melatonin levels are associated with erectile dysfunction

Int. braz. j. urol; 44 (4), 2018
ABSTRACT Objective: Melatonin is a hormone secreted from the pineal gland and has anti-oxidative and anti-inflammatory effects. Oxidative stress is considered as an important factor in the etiology of erectile dysfunction (ED), and in many experimental models, positive results have been obtained with me...

Liver ischemia and reperfusion injury. Pathophysiology and new horizons in preconditioning and therapy

Acta cir. bras; 33 (8), 2018
Abstract It is well known that during hepatic operative procedures, it is often critical that the irrigation is interrupted to avoid possible bleeding, blood transfusions, variable intensities, and their short and long-term consequences. It was believed in the past that the flow interruption should not e...

The role of vitamin C in the gene expression of oxidative stress markers in fibroblasts from burn patients

Acta cir. bras; 33 (8), 2018
Abstract Purpose: To assess the action of vitamin C on the expression of 84 oxidative stress related-genes in cultured skin fibroblasts from burn patients. Methods: Skin samples were obtained from ten burn patients. Human primary fibroblasts were isolated and cultured to be distributed into 2 groups:...
